Beam Transmissometers for Oceanographic Measurements
The theoretical basis for the measurement of the beam transmittance of water is reviewed. Existing data for the beam transmittance of clean and distilled water are compared to demonstrate the current state of knowledge regarding the beam transmittance of clean water. Several recent instruments of sophisticated design are briefly described and data are given for surface particle concentration.
